SPECIFICATION forming part of Letters Patent No. 397,819, dated February12, 1889.

Application filed June 9, 1888. Serial No. 204,673. (No model.) A

To alZ whom it may concern:

Be it known that 1, JAMES CAMILLE ROSSI,

of Perth Amboy, in the county of Middlesex I and State of New Jersey,have invented cer- 5 tain new'and useful Improvements in Machines forManufacturing Ice, of which'th-e following is a specification, referencebeing had to the accompanying drawings.

My improvements consist of. apparatus IO working upon the generalprinciple andopcrating in accordance with themethod set forth in myUnited States patent,No. 300,133, dated June 10, 1884, so far as theidea of continuous action is concerned. 7 r

My object is to produce a simple, economical, convenient, andcontiuuously-operating apparatus,whieh may be of varying sizes andcapacity, to be used mainly for the manufacture of ice. v

.I provide a series of contiguous tubsor'vesselsof any desired form, butas represented in the drawings, and as I think generally preferable, ofcircular form, one si irrounding another, the central one being thefreezer, and the-others, whether one, two, ormore, I term theeconomizers. that I keep up a continuous supply of water, underpressure, that is cooled in the economizers on its way to the freezer,where a' proper chemical salt for reducing the temperature by beingdissolved is supplied with practical continuity. The dischargeof the.

which the salt-feeder, and with it the can impure water, or that whichhas been impregnated with the salt from the freezelgis by overflow tothe first economizer and then to the other or others, and finally out ofthe last. as awaste solution to evaporators 01' suitable condensers.-

In the accompanying drawings,illustrating myimproved apparatus, Figure lis a vertical central section, and Fig. 2 is a horizontal section on theline 2 2 of Fig. 1.

Referring to the letters upon the drawings in aid ofadetaileddescription'of this particular form of the apparatus, which Ideemthe best form of this peculiar machine, A indicates' the freezer,which is a central cylindrical vessel made of wood or paper pulp, for

- the sake of lightness, cleanness, andnon-ac ,50 tion of the solutionon the material.

lhe structure is such in the pipe. From the pipe K the water. is

tur'es, into which are inserted the cans N N,

. B and C are economizers, being cylindricalvessels surrounding thefreezer, and of similar material, and containing coils F F. Thesethreevessels are carried on .the platform U, movable, for convenience,on Wheels U U. PipesY are provided at the bottom for emptying thesevessels through a cook or valve, Y. The freezing-vessel A may beprovided with a perforated false bottom, L, of similar material to thatof the vessel. At the upper part of the interior of the vessel A-areprojections b l), which are arcs of a circle and constitute the supportor hearing of the can-holder R,

which is simply a support of wood with apercontaining water to befrozen. These may be of any desired form, and are held in place byprojections F near their tops, and provided with covers Q, preferably ofWood.

N indicates the salt-feeder, which passes through the cover of theapparatus, through the can-holder, and down through the vessel A, andrests upon a block or socket, M. It is a hollow cylinder of tin orpaperor wood pulp, perforated along its lower part by numerous large holes,0, and carrying atthe top a hopper or a funnel, as shown. Thissaltteeder is made fast to'the can-holder by any suit-ablemeans, such asplates and screws X.

W W indicate parts fixed to the upper part of the salt-feeder above thecover of the ap paratus, provided with handles S, by means of holderRand cans, can be oscillated to agitate the liquid in the vessel A. f 05An opening, 19, is provided for the overflowv from the vessel A intovessel B, and an. opening,-'n, isprovided for overflow from the vessel Binto the vessel 0, which latter overflows by'nieans'of the pipe m intoevaporators or vessels. (Not shown.)

' The feed-water is supplied from a reservoir or hydrant, D, underpressure. It tlowsthrough the pipes E E into coil F. in vessel 0, andreaching the connection G into the coil F of vessel B, andfrom'there bythe pipe H, provided with a valve, V,through the pipe K, preferablysurrounded by an envelope of paper-pulp, K, to prevent the freezing ofwater delivered downward into the vessel A beneath F the false bottom L,as indicated by the arrows. Then the feed-water strikes the salt chargedat the start in freezer A through salt-feeder M, it dissolves the salt,producing an intense cold, which, being transmitted to the ice-cans N,freezes the water they contain, or, more properly speaking, absorbs theheat of the water they contain, so as to congeal it. The

A, overflows into vessel C", and further cools the feed-water flowingthrough. coil F of yessel C. Finally the solution overflows from vesselC through pipe m to evaporators, or to f be utilized to cool distilledwater for drinking purposes in a water-cooler,-or for cooling water tobe used to fill ice-cans, or for any other cooling purpose. As the coldwater dissolves the salt contained in vessel A and in the lower part ofthe salt-feeder tube M, the salt drops in the salt-feeder M by gravity,taking the place of that which has been dissolved. More salt is suppliedas the hopper is emp-l tied, andv the process of freezing continues inthe cans N.

A trap or regulator, T, of ordinary kin d, may be provided to regulatethe feed of the salt from the hopper into the tubular part of thesalt-feeder. By a proper regulation 'of the admission-valve V on thefeed-water pipe II and of the delivery-valve X of the reservoir orhydrant D, it is easy to provide a proper supply and flow of water, andsalt can be supplied, so that the freezing will continue constantly, theonly interruption being the removal of the ice made and the replacing ofcan-holder, R, resting upon supports b and adapted to be oscillated, thesalt-feeder so:

the cans N filled with pure. water for freezing. It is not necessary toagitate the i'reezing-solution in vessel. A; but the operation of 5handles S and block M and surrounded by freezing will be promoted by sodoing. It is not. absolutely necessary to employ the false bottom L, butgenerally desirable.

The lower end of the pipe K might be in the form of a nozzle orsprinkler to divide the inflow of feed-water to vessel A into numer ou'sjets. y

I do not confine my invention to the precise form ofappa'ratus shown,because varioi'ls formal changes niiglitbe made. For example, 2

coils F F are merely provided to give a greater extent of flow of the.water-supply and more time for cooling; but any other form of pipe mightbe adopted, although I think coils preferable. The vessels or tubs(freezer and economizers) might be contiguous and not concentrical toeach other. They might be put in line close together and one after theother, or in the shape of a tria'l'igle, i t two economize-rs be used,or of a rectangle it" three economizers be used; butthc concentric formis generally preferable. The mode of operation in. any of thesedispositions is substantially the same. 7

Of course it will be understood that the water at first inflowing willnot be cooled until it reaches the freezer, the special coolingoperation of the infiowing water only beginning outside of the freezerafter it has been filled and the overflowhas commenced; but in prac:

- tice this is immediately after the operation be -ins so that ver soonthe water that comes b r 5 1n contact with the salt to be reduced 1ntemperature will have been already materially reduced in theeconomizers, so that the salt in the freezer does its work with greatperfection. Of course a cold solution might be. placed in theeconomizers before the inflow commences, and this may be done. wheneverdesired.

Having thus described my machine, whatI claim as new, and desire tosecure by Letters Patent of the United States, is-

1. In an ice-machinedhe combination of the freezing-vessel A, providedwith the canholder R, resting upon supports 1) and adapted tobe'oscillated, the salt-feeder secured to the can-holder and providedwith handles S, the

block M, for supporting the lower end of the.

can-holder in its socket, so that the oscillation of the canholder andcans can beeileeted, substantially as set forth.

2. In an ice-machine, the combination of a central freezing-vessel, A,provided with a cured to the can-holder and provided with ALFRED EUCLIDPOIRIER, Janus LEWIS (ionr'ron
